Sandbox, as his name suggests, is a living creature made of a pale yellow, sand-like material. He has brown, wood armor on his back and arms. He has some black clothing on the top of his head with a white stripe. He has green eyes just beneath this clothing, and the Omnitrix on it.
- As Sandbox's body is made of a sand-like material, he has sand physiology. This gives him the ability to shapeshift at will. He also can change the density of his sand, changing himself between sandstone and regular sand. The wooden armor on his body changes to be compatible with whatever he does with hte rest of his body.
- Sandbox can regenerate from hits easily.
- Sandbox's sandstone has enhanced durability, and his sand is virtually indestructible by nature due to how sand acts, paired with his regeneration.
- Sandbox can easily be used as a stealth alien.
- Intense heat can change Sandbox's sand to glass, making him extremely fragile. His wooden armor can also catch on fire.
- Water can turn his sand to mud. While this can be used against enemies, it is more often than not an issue for himself as it no longer acts like the rest of his body.
- Sandbox's debut was in the Tempparatus Files in The More They Stay the Same when he was shown replacing Bloxx in The More Things Change: Part 1.
